Dr is suppose to call me and let me know if I need more tests done, and give me more info. It's been 2 weeks. How long should I wait before calling?

Call. Now. Likely, there was a miscommunication and no one will be offended if you initiate the conversation again. I encourage all my patients to call within a few days if they don't hear from the office. Unfortunately, we all get very busy and try as we might to avoid, things do fall between the cracks.
